The Dragon cargo ship, operated by the private spaceflight company SpaceX, arrived at the International Space Station on Sunday morning

It's not exactly the Easter bunny, but a commercial Dragon cargo ship built by SpaceX made an Easter delivery to the International Space Station Sunday (April 20) to deliver tons supplies, and possibly even some treats, for the astronauts on board.

The roboticDragon spacecraftarrived at space station Sunday morning, floating within reach of the orbiting laboratory's robotic arm. Station astronauts used the arm to capture the Dragon spacecraft as both spacecraft sailed 260 miles (418 kilometers) above Egypt and the Nile River.

"Great work catching the Dragon," NASA astronaut Jack Fischer radioed the station crew Mission Control in Houston. The station crew then carefully attached the Dragon cargo ship to a docking port on the station, completing the job in just under three hours.

The Hawthorne, Calif.-basedSpaceXlaunched the Dragon cargo ship toward the space station on Friday (April 18) using its own Falcon 9 rocket that lifted off from Cape Canaveral Air Force Station in Florida. The mission is SpaceX's fourth Dragon flight to the space station and third of 12 cargo delivery missions under a $1.6 billion deal with NASA.

The Dragon spacecraft is carrying 5,000 lbs. (2,268 kilograms) of food, supplies and gear for 150 different experiments. A miniature lettuce farm, space robot legs and laser communications system are among the delivery's highlights.

Bill Gerstenmaier, NASA associate administrator for human exploration and operations, said Friday that he wasn't sure if those supplies included any chocolate eggs, jelly beans or other Easter goodies for the station crew.

"It'll be a surprise for all of us when they open the hatch," Gerstenmaier said. That hatch opening is slated to occur on Monday.

SpaceX Dragon capsule makes Easter delivery to space station

When the SpaceX-3 cargo resupply mission launched to the International Space Station April 18, an experiment designed by NASA's Jet Propulsion Laboratory in Pasadena, Calif., was among the cargo headed to space.

The experiment, Optical PAyload for Lasercomm Science (OPALS), will test the potential for using a laser to transmit data to Earth from space. Instead of being broadcast on radio waves, data is packaged onto beams of laser light and pointed to a receiver station on the ground. Radio wave transmissions are limited by the speed they can transfer data, but beaming information packages with lasers can greatly increase the amount of information transmitted over the same period of time.

SpaceX-3 is NASA's third contracted resupply mission to the space station by U.S. company SpaceX of Hawthorne, Calif. SpaceX's Dragon spacecraft launched atop the company's Falcon rocket from the Cape Canaveral Air Force Station in Florida at 3:25 p.m. ET.

SpaceX developed its Dragon capsule, the only cargo spacecraft currently servicing the space station with the capability to return cargo back to Earth, with NASA and now successfully has completed three missions to the orbiting outpost. Expedition 39 crew members captured the SpaceX-3 Dragon using the station's robotic arm at 7:06 a.m. Sunday, April 20. The capsule is scheduled to remain attached to the station until May 18. It then will return to Earth and splash down in the Pacific Ocean, off the coast of California. It will return samples from scientific investigations currently underway aboard the space station.

The International Space Station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has had continuous human occupation since November 2000. In that time, it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.
